What is the area of ​​a wind turbine blade?

Introduction What is the surface area of ​​a wind turbine blade? The wind energy utilization coefficient of the wind turbine is expressed by CP. In theory, CP will not exceed 0.593. Nowadays, traditional wind turbines have the largest electricity production.

What is the area of ​​a wind turbine blade?

The wind energy utilization coefficient of the wind turbine is expressed by CP. Theoretically, the CP will not exceed 0.593. The maximum power generation efficiency of current traditional wind turbines (the highest utilization rate is about 10 meters/second). generally around 0.45, while the seventh level wind is 14 to 17 meters/second, which exceeds the annoying wind speed of the fan, and the utilization rate will begin to decrease, around 0.2 to 0.4. The sweeping area is related to the diameter of the wheel. The current diameters of the main wheel are 70, 80, 93, 105, 115 meters, etc. You can calculate the corresponding scanning area.

In addition, the current power of main wind turbines is 1500, 2000, 3000, 5000, 6000 kW, etc., of which 1500 and 2000 account for 80%.

The 120 meter high wind turbinegenerates around 2.5 kilowatt hours of electricity in a single revolution Although the blade. the speed is not high, but the gearbox inside the generator can increase the speed of the high-speed shaft to 50 times that of the low-speed shaft. Based on a wind turbine's power output of about 1,500 kilowatt hours per hour, the wind turbine can generate 2.5 kilowatt hours of electricity when it spins once and then converts the energy wind turbine into electrical energy. converts it into usable electrical energy by inversion. The available electrical energy can then be used to operate electronic devices.

The principle of wind energy

A normal-sized wind turbine can generate an average of 1,200 kilowatt hours of electricity per hour in conversion. a large windmill spins once, it can generate about 1 kilowatt hour of electricity. The windmill is limited by the material structure and is designed to have a maximum speedthe which will damage the windmill itself, or even destroy it completely.

The conversion of wind energy into electrical energy is also a complex process. In traditional wind turbines, after the blades rotate, the rotation speed is increased through several sets of gears such as speed multipliers to drive the generator to produce electricity. However, this method consumes a lot of energy, so another technology has been developed, direct drive permanent magnet technology.
